Marble Hatchetfish

Marble Hatchetfish — an elegant surface-dweller that brings shimmering, sculptural movement to planted aquariums and community tanks. Sourced and curated by Tropical Exotics, this striking species is prized for its unique hatchet-shaped body, marble-like patterning, and active schooling behavior.

Why aquarists love the Marble Hatchetfish:

• Distinctive appearance: Silvery, compressed bodies with marbled patterns reflect light at the water's surface, creating a living accent piece for any aquarium.
• Peaceful community member: Gentle temperament makes them ideal companions for other non-aggressive mid- and top-dwelling species.
• Active surface swimmers: Energetic schooling habits add dynamic movement and visual interest to planted tanks and open-top displays.
• Reliable from Tropical Exotics: Responsible sourcing and careful acclimation ensure healthy, hardy fish ready for your aquarium.

Care & tank recommendations

• Tank size: 20+ gallons for small schools; larger tanks recommended for groups to display natural schooling behavior.
• Water: Soft to moderately hard, pH 6.5–7.5, stable temperatures between 74–79°F (23–26°C).
• Environment: Provide dimmed lighting, floating plants or surface cover, and open surface area for natural swimming patterns.
• Diet: Omnivorous — accept high-quality flake, micro-pellets, and frequent small live/frozen foods (daphnia, brine shrimp) to promote vibrant color and health.
• Behavior: Best kept in groups of 6 or more to reduce stress and showcase shoaling displays.

Perfect uses

• Community freshwater aquariums seeking a peaceful top-dweller with visual flair.
• Planted setups where surface activity enhances the ecosystem's depth and movement.
• Show tanks and public displays where the Marble Hatchetfish's reflective sheen and schooling behavior make a striking impression.
